Has a REST API you can send and receive messages through. They can store contact lists for you, deniably they claim. Accepts cryptocurrency for payment.
A curated list of telco resources and projects.
Please note multiple researchers published and compiled this work. This is a list of their research in the 3G/4G/5G Cellular security space. This information is intended to consolidate the community's knowledge. Thank you, I plan on frequently updating this "Awesome Cellular Hacking" curated list with the most up to date exploits, blogs, research, and papers.
You're welcome, Internet.
At Futel, we believe in the preservation of public telephone hardware as a means of providing access to the agora for everybody, and toward that goal we are privileged to provide free telephone calls, voicemail, and telephone-mediated services. We do not judge the motivations of our users, or who they choose to call; if they don’t have someone to call, we can provide a presence on the other end. Denial of telephony services has long been a tactic used against undesirable populations, and our devices will counteract that. But more importantly, we will help to establish a new era of communication, one in which reaching out is not only desirable, but mandatory.

A small hobby software PBX for the tildeverse. So far users can make calls, leave voicemails and participate in a multi-user conference with more features to come. The numbers are loosely broken down by tilde, with each tilde having its own prefix "area code." It's set aside for tilde users only, and is not connected to the PSTN - you have to be an active tilde user just to get the admin's attention.
A group of telephony hobbyists who restore and maintain old equipment. They figure out how to get their gear VoIP-enabled and built their own PSTN on top of the Net by hooking everything together. It's pretty serious, plus they document their work pretty well.
How to create a portable GSM BTS which can be used either to create a private ( and vendor free! ) GSM network or for GSM active tapping/interception/hijacking … yes, with some (relatively) cheap electronic equipment you can basically build something very similar to what the governments are using from years to perform GSM interception.
An archive of recordings from the early days of phone phreaking- stuff like conversations recorded off of bridges, tone sequences, war stories, stuff like that.
A security testing application that determines if Cisco VoIP hardware is in use, and if so drops the attacking box onto the VoIP VLAN by impersonating an IP telephone through a new virtual interface.
An online service that acts as a telephony middleman - you tell them what number to call, what number you want to show up on both Caller ID and the bill, and what your number is, and they'll connect the two numbers with the spoofed information of your choice.
A lengthy how-to article about building an open source PBX using Linux and Asterisk that uses wireless for its network link. A fully portable wireless telephony system, in other words.
An archive of recorded messages and error tones from United States telephony networks. Available for online listening or free download.
UCSniff is a VoIP & IP Video Security Assessment tool that integrates existing open source software into several useful features, allowing VoIP and IP Video owners and security professionals to rapidly test for the threat of unauthorized VoIP and Video Eavesdropping. Written in C/C++, and available on Linux and Windows, the software is free and available for anyone to download, under the GPLv3 license.
Adafruit sells working 2G SIMcards for use in telephony enabled projects. hacking hardware The manufacturer/provider is Ting. GSM Pay as you go provider, kind of like voip.ms.
The Test Call is the homepage of a free (and legal!) service that offers some telephony debugging services, such as echoback (say something, it records it and plays it back), DTMF identification, a 4KHz sweep for audio quality, and caller ID checking.
